It is not necessarily the ASAMO component, because that is for reporting, and most likely not EP. Check the AX System Requirements guide that which components are required for deploying EP, those are the suspicious ones which you should verify.
Here are some example topics which were resolved by putting on the correct prerequisites, however, they were not for EP but Reporting:

This is the reason why I suspect it might be related to an incorrect deployment of a prerequisite component, or AX initialization/firewall/antivirus issue.
